A's announce Opening Day tickets sold out

PHOENIX -- It's official: The A's will open the 2013 season in front of a sold-out crowd at O.co Coliseum on Monday.

Coming off an American League West title, the A's announced Wednesday afternoon that Opening Day had become a sellout, with ticket sales reaching capacity days earlier than last year. In 2012, the team opened the season against the Seattle Mariners in Japan for two games on March 28-29 and then played their home opener on April 6, also against the Mariners.

The A's will take on the Mariners Monday on Opening Day, once again with left-hander Brett Anderson starting for the A's and Felix Hernandez for the Mariners in a 7:05 p.m. PT first pitch. It will be the first game of a four-game set that ends on Thursday afternoon.

The first 32,000 fans at Monday's opener will receive a gold rally towel and a magnetic schedule.
